Molecular Dynamics of Glassy Materials (image) University of Chicago Caption Fast-acting molecules organize themselves more randomly (left) under certain temperature conditions than slower-acting, more systematically organized molecules. The more systematically organized molecules (right) lend greater stability and technological value to glassy materials.
